Performance Data

  • Flow Measurement Uncertainty
    • Selected Sensors down to ±0.05 % ¹ of rate (Gold Line)
    • Standard Sensors down to ±0.15 % ² of rate
  • Flow Measurement Repeatability : Down to ±0.05 % of rate
  • Temperature Measurement : Better than ±1 °C
  • Density Calibration (Liquid) :
    • Selected Sensors down to ±0.000  :  5 kg/liter (Gold Line)
    • Standard Sensors down to ±0.0035 kg/liter :
  • Uncertainties and flow measurement turn-down
    • The turn down capability from Qₙₒₘ of the flow sensor is driven mainly by its zero point stability. At the very low end of the measuring range the uncertainty (u) is dominated by zero point stability. The zero point stability of a standard sensor is: 0.000036 kg/min (0.000079 lbs/min). Zero point stability of a Gold Line sensor is 0.000019 kg/min (0.000042 lbs/min).
      • For flow Q ≥ ZP stability / (Base Calibration uncertainty/100) → u = calibration uncertainty
      • For flow Q < ZP stability / (Base Calibration uncertainty/100) → u = (zero stability/Q) * 100
  • Uncertainties from environmental and process conditions
    • If sensors are not zeroed at operating conditions, minor additional uncertainties can arise from elevated temperatures and pressures: ±0.00308 % of maximum flow per °C and ±0.0208 % of maximum flow per bar.
    • Process temperature effect on density: additional uncertainty of ±0.000641 g/cm³ per °C difference from calibration temperature with standard density calibration and of ±0.000073 g/cm³ per °C difference from calibration temperature with enhanced density calibration. This effect can be mitigated by a simple field density adjustment at operating conditions.
    • Process pressure effect on mass flow: The effect of pressure on flow measurement is 0.001 % of rate per bar. Compensation is possible by pressure sensor input (analog input or digital write) or manual value entry into the transmitter.
    • Process pressure effect on density: The effect of pressure on density measurement is 0.00012 g/cm³ per bar. Compensation is possible by pressure sensor input (analog input or digital write) or manual value entry into the transmitter.
  • Premium Plus, Ultimate, Low Flow and Enhanced Density Calibration come with Gold Line sensors and are not available in all materials, pressure and temperature ranges.
  • Reference conditions: 18-24°C Water @ 1-3 bar; Gas (Natural gas) 35-100 bar.

Measurement Tube Pressure Ratings

The maximum pressure (pₘₐₓ) of a sensor is determined by its lowest rated part. The lowest rated part can be either the measurement tube (pₘₐₓ indicated below), the connection block/manifold (pₘₐₓ indicated in the mechanical construction section) or the process connection (for pₘₐₓ see published standards or manufacturer information).
